The study, published in the latest issue of the journal Current Biology, found that fish grew larger in small traditionally managed reserves, rather than in larger national parks and most co-managed reserves run by several partner organizations. The authors also found that traditionally managed reserves did not permanently close fishing around reefs, a technique often touted by managers as the best way to safeguard fish stocks. Instead communities occasionally opened their reserves to obtain food for feasts – an important incentive to ensure that temporary closures were enforced.
"This study clearly shows that communities with a direct stake in preserving healthy fisheries around reefs can often serve as the best managers and police to protect these areas from overfishing," said WCS biologist Dr. Tim McClanahan, the study's lead author. "Governments wishing to establish marine protected areas can learn a valuable lesson that communities must see some benefit of closures to ensure their participation and adherence to the rules."
The authors looked at a total of four national parks, four-co-managed reserves and three traditional reserves in Indonesia and Papua New Guinea, finding that traditional reserves were often managed to meet community needs, not strict conservation goals established by outsiders. These reserves also tended to be located in remote areas with small human populations, with limited influence by outsiders and markets. The one co-managed reserve that enjoyed similar results found in traditional reserves was established after careful consultation with the community along with considerable donor support.
On the basis of their findings, the authors propose that while large, permanent marine protected areas may provide the best protection for species that are at particular risk from overfishing, a combination of such large marine protected areas and traditionally managed systems may represent the best overall solution for meeting conservation and community goals and reversing the degradation of reef ecosystems. Other authors of the study include Michael J. Marnane of the Wildlife Conservation Society; Joshua E. Cinner of the Centre of Excellence for Coral Reef Studies, James Cook University in Townsville, Australia; and William Kiene of Fagatele Bay National Marine Sanctuary in Pago Pago, American Samoa.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
